Question

5 cosec square 60 + 4 cos square 30 - tan square 45 / sin square 30 +cos square 30

​

Answer 1

Answer:

solve:- 5 cosec sq. 60 + 4 cos sq. 30 - tan sq. 45/sin sq. 30 + cos sq. 30

= 5x4/3 + 3 - 4 + 3/4

=77/12 is answer

formula :- cosec60 = 2/√3 , cos30 = √3/2 , sin30 = 1/2 , tan45 = 1
